We should avoid including the whole of softfloat headers in cpu.h and
explicitly include it only where we will be calling softfloat
functions. We can use the -types.h in cpu.h for the few bits that are
global. We also move the restore_snan_bit_mode into internal.h and
include -helpers.h there.

Note that env->active_tc.PC is removed from the qemu_log as that value
is garbage. The PC isn't recovered until cpu_restore_state, called from
cpu_loop_exit_restore, called from do_raise_exception_err.
Backports commit 931d019f5b2e7bbacb162869497123be402ddd86 from qemu
Implement hardware page table walker. This implementation is
limiter only to MIPS32.
Backports commit 074cfcb4daedf59ccbbbc83c24eee80e0e8f4c71 from qemu
Do following replacements:
ASE_DSPR2 -> ASE_DSP_R2
ASE_DSPR3 -> ASE_DSP_R3
MIPS_HFLAG_DSPR2 -> MIPS_HFLAG_DSP_R2
MIPS_HFLAG_DSPR3 -> MIPS_HFLAG_DSP_R3
check_dspr2() -> check_dsp_r2()
check_dspr3() -> check_dsp_r3()
and several other similar minor replacements.
Backports commit 908f6be1b9cbc270470230f805d6f7474ab3178d from qemu
Add infrastructure for availability control for DSP R3 ASE MIPS
instructions. Only BPOSGE32C currently belongs to DSP R3 ASE, but
this is likely to be changed in near future.
Backports commit 59e781fbf13a2dede15437d055b09d7ea120dcac from qemu
Increase the size of insn_flags holder size to 64 bits. This is
needed for future extensions since existing bits are almost all used.
Backports commit f9c9cd63e3dd84c5f052deec880ec92046bbe305 from qemu
The MC68040 MMU provides the size of the access that
triggers the page fault.
This size is set in the Special Status Word which
is written in the stack frame of the access fault
exception.
So we need the size in m68k_cpu_unassigned_access() and
m68k_cpu_handle_mmu_fault().
To be able to do that, this patch modifies the prototype of
handle_mmu_fault handler, tlb_fill() and probe_write().
do_unassigned_access() already includes a size parameter.
This patch also updates handle_mmu_fault handlers and
tlb_fill() of all targets (only parameter, no code change).
Backports commit 98670d47cd8d63a529ff230fd39ddaa186156f8c from qemu
Register separate QOM types for each mips cpu model,
so it would be possible to reuse generic CPU creation
routines.
Backports commit 41da212c9ce9482fcfd490170c2611470254f8dc from qemu
no logical change, only code movement (and fix a comment typo).
